And I still believe we need to drive a stake through its heart at some
point and actively kill it. Basically to say "you can use v4 if you
want in private networks or between individual networks but it isn't
going to be supported ubiquitously on the global Internet after $DATE".
The reason is that the bailing wire, super glue, rubber bands, and
chewing gum needed to continue supporting it results in a mess. At some
point networks will be staffed with techs that never even learned v4 in
school.
